Description

  The present invention relates to a simple filter attachment jig for attaching a sheet-like simple filter so as to cover an existing filter attached to an air conditioning or ventilation facility.

In general, an air conditioner installed in an office or home has a built-in filter for removing dust contained in the air taken in.
However, if the air conditioner is used for a long period of time, the filter will be clogged and the dust removal capability will be reduced.
Therefore, it is necessary to periodically clean the filter, but since many air conditioners are installed in large-scale facilities, it takes a lot of time to clean the filters of all air conditioners. I need.

Therefore, in large-scale facilities where many air conditioners are installed, spare filters are stocked, and the filters that become dirty with use are regularly replaced with spare clean filters. The work of cleaning the filter is omitted.
However, such a conventional method has a problem in that extra costs such as storage costs are incurred because it is necessary to stock a large number of spare filters.

In view of the above situation, a method for reducing the number of times of cleaning the filter of the air conditioner has been proposed.
For example, in the following Patent Document 1, a sheet-like auxiliary filter is detachably fixed between a grill panel and an existing filter, thereby reducing the amount of dust attached to the existing filter and reducing the number of times the filter is cleaned. Is disclosed.
In the method described in Patent Document 1, the auxiliary filter is detachably fixed to the grill panel by fitting an elastically deformable fixture such as rubber into the groove of the grill panel while holding the auxiliary filter. To do.
However, since the fixture used in this method needs to match the shape of the groove, the versatility is poor. Actually, since there are various types of air conditioners, various types of fixtures corresponding to the forms are required.

Patent Document 2 listed below describes a method of fixing an air conditioning filter with a perforated hole to a grill cover using a fixture made of a tension spring type hook.
However, since four fixing tools are required to fix one air conditioning filter, there is a problem that it takes a long time to install and remove, and the working efficiency is very poor.

In offices and the like, the air conditioner outlet is often provided on the ceiling. However, dirt such as soot may adhere to the ceiling around the outlet and darken.
Therefore, in order to prevent diffusion of wrinkles from the blowout port, a filter in which a nonwoven fabric is sewn in a circular ring may be mounted in a pipe connected to the blowout port.
However, such a filter is usually made-to-order and expensive, but when the cleaning is repeated 3 to 4 times, the seam is broken and cannot be used. Therefore, it is necessary to prepare a new filter frequently, and there is a problem that the maintenance cost becomes high.
Moreover, since the filter is circular and is mounted in the pipe, it is not possible to use a fixture as disclosed in Patent Documents 1 and 2.

Also, in factories and the like, ducts for taking outside air into the room are sometimes installed on the ceiling, etc., but when sand or dust contained in the outside air enters the room through the duct, There is a problem in that there is a risk of harming the health of the person or adversely affecting equipment such as machines.
In order to prevent the intrusion of sand and dust from the duct, for example, it is conceivable to install a circular filter that matches the inner cross-section of the duct inside the duct. However, since it is not possible to use a fixing tool as disclosed in Patent Documents 1 and 2 for a circular filter mounted in a duct, it is necessary to frequently replace the filter.

Further, in a large-scale facility or the like, an indoor circulation type ventilation device may be installed.
Usually, a filter is attached to the suction port of the indoor circulation type ventilation device in order to remove dust present in the indoor air.
However, if the ventilator is used for a long period of time, the filter will be clogged and the dust removal capability will be reduced. Therefore, it is necessary to periodically clean the filter. As a result, the above-described air conditioner The same problem occurred as in.

JP 2003-240329 A Utility Model Registration No. 3143236

  The present invention has been made in order to solve the above-described problems of the prior art, and a simple sheet-like filter can be easily added to an existing filter built in various types of air conditioners. The same is true for existing filters that can be securely installed, or installed in advance or retrofitted to an air conditioner outlet provided on the ceiling, a duct for taking outside air into the room, an indoor circulation ventilator, etc. It is an object of the present invention to provide a highly versatile simple filter mounting jig capable of easily and reliably mounting a simple filter.

  The invention according to claim 1 is a jig for attaching a sheet-like simple filter so as to cover an existing filter mounted on an air conditioning or ventilation facility, and an annular body disposed in the center, An elastic body that can extend and contract from the annular body in all directions, and a ring-shaped member that is provided at the tip of the extending direction of the elastic body, the ring-shaped member being the elastic body The present invention relates to a simple filter mounting jig characterized in that a linear portion that is substantially perpendicular to the extending direction of the elastic body is provided in the vicinity of the connecting portion.

  In the invention according to claim 2, the distal end portion of the elastic body and the proximal end portion of the ring-shaped member are coupled via a coupling member, and the coupling member rotates with respect to the distal end portion of the elastic body.

  The invention according to claim 5 relates to the simple filter mounting jig according to any one of claims 1 to 4, wherein the length of the linear portion can be adjusted.

According to the first aspect of the present invention, the annular body disposed at the center, the elastic body that can extend and contract from the annular body in all directions, and the distal end of the elastic body in the extending direction are provided. Since the sheet-like simple filter is put on the existing filter built in the air conditioner, the jig is fixed to the existing filter from above the simple filter. And a simple filter can be reliably attached to an existing filter.
Specifically, the jig is attached to existing filters of various sizes and thicknesses by extending the elastic body in all directions and locking the ring-shaped member at the tip to the four corners of the existing filter. It becomes possible to attach the simple filter by fixing it easily and surely.
In addition, since a plurality of jigs are not required for attaching one simple filter, it is possible to efficiently perform attachment and removal work in a short time.
In addition, since the ring-shaped member has a linear portion that is substantially perpendicular to the extending direction of the elastic body in the vicinity of the connecting portion with the elastic body, the ring-shaped member has four corners of the existing filter. When the ring-shaped member is locked, the base end portion of the ring-shaped member is expanded by the linear portion, and the lock is hardly released.
Furthermore, the simple filter can be easily and reliably attached to the existing filter attached to the suction port of the indoor circulation type ventilation device by the same method.

According to the second aspect of the present invention, the connecting member that connects the ring-shaped member and the elastic body includes the attachment portion that is rotatably attached to the distal end portion of the elastic body. The angle of the member with respect to the elastic body can be freely changed, and it can be widely applied to existing filters of various sizes and thicknesses.
In addition, since the connecting member includes a holding portion that holds the linear portion of the ring-shaped member, the linear portion can be reliably formed even when a flexible wire is used as the ring-shaped member. .
Further, since the connecting member is formed in a substantially T shape as a whole, the ring-like member provided at the tip of one elastic body is locked to the connecting member provided at the tip of another elastic body. be able to. For this reason, it is possible to attach a simple filter to a circular filter that does not have corners, and a pipe connected to the air conditioner outlet provided on the ceiling or the inside of a duct for taking outside air into the room. A simple filter can also be attached to the filter attached to. In other words, the filter mounting jig can be applied regardless of the shape of the existing filter and has excellent versatility.

  According to the invention of claim 3, since the holding portion of the connecting member is formed in a flat shape, when the ring-shaped member is locked to the four corners of the existing filter, the flat shape of the holding portion is Since the surface hardly moves in close contact with the surface of the simple filter, the locking of the ring-shaped member is further less likely to come off.

According to the invention of claim 4, since the base end portion of the elastic body is movably attached along the annular body, the arrangement of the elastic body relative to the annular body can be freely changed, It can be widely applied to existing filters having a size and thickness.
In addition, when not in use, the elastic body and the ring-shaped member can be overlapped with each other. Therefore, the jig is not bulky during storage and transportation of the jig, and the storage space can be reduced.

Hereinafter, a preferred embodiment of a filter mounting jig (hereinafter simply referred to as a jig) according to the present invention will be described with reference to the drawings.
FIG. 1 is an overall view of a jig according to the present invention.
The jig (1) according to the present invention is a jig for attaching a sheet-like simple filter so as to cover an existing filter mounted in advance or retrofitted to an air conditioning or ventilation facility.
The jig (1) includes an annular body (2) disposed in the center, a stretchable elastic body (3) extending from the annular body (2) in four directions, and an extension of the elastic body (3). A ring-shaped member (4) provided at the distal end in the installation direction, and a connecting member (5) for coupling the distal end of the elastic body (3) and the base end of the ring-shaped member (4) are provided. .

The annular body (2) is a circular ring, and is formed, for example, by processing a metal wire into a circle.
The elastic body (3) is made of an elastic member such as rubber or a spring, and a coil spring is used in the illustrated example. When using a coil spring, it is preferable that the diameter is small. Specifically, it is preferably 10 mm or less, and more preferably 5 mm or less. This is because, when the diameter is large, when the jig is attached as will be described later, the thickness of the jig becomes an obstacle and the louver or the like cannot be closed.

There are a total of four elastic bodies (3), and the base end portion of each elastic body (3) is attached to the annular body (2). The number of elastic bodies (3) is most preferably four, but may be five or more (for example, six or eight).
An annular portion (31) is formed at the base end of the elastic body (3), and the annular portion (31) is engaged with the annular body (2). Thereby, each elastic body (3) can move along the annular body (2) (see arrow in FIG. 2).
Thus, since each elastic body (3) is movable along the annular body (2), the arrangement (direction) of the elastic body (3) with respect to the annular body (2) can be freely changed. Therefore, it can be widely applied to existing filters having various sizes, thicknesses, and shapes.
In addition, when not in use, the elastic body (3) and the ring-shaped member (4) can be stacked (see FIG. 3), so that they are not bulky when storing and transporting jigs, and have a space for storage and the like. It's small.

The ring-shaped member (4) is formed from a thin wire having flexibility that can be freely deformed, and is preferably formed from a thin metal wire from the viewpoint of strength. However, in the present invention, the material of the ring-shaped member (4) is not limited to a metal wire, and may be formed of an elastic material such as rubber. In this case, since the size can be freely changed by deforming the ring-shaped member (4) during use, the versatility of the jig can be improved.
The ring-shaped member (4) has a linear portion (41) that is substantially perpendicular to the extending direction (stretching direction) of the elastic body (3) in the vicinity of the connecting portion with the elastic body (3). Yes.

The connecting member (5) includes a holding portion (51) for holding the linear portion (41) of the ring-shaped member (4) and an attachment portion (52) attached to the tip of the elastic body (3). Yes.
The connecting member (5) is a substantially T-shaped member formed from a metal material, the attachment portion (52) is formed from a thick metal wire, and the holding portion (51) is formed from a metal cylindrical body. ing. Then, by inserting the proximal end portion of the ring-shaped member (4) and the distal end portion of the attachment portion (52) into the cylindrical body constituting the holding portion (51), the cylindrical body is caulked flatly. Thus, the distal end portion of the attachment portion (52) and the proximal end portion of the ring-shaped member (4) are connected via the holding portion (51).

Thus, since a connection member (5) is provided with the holding | maintenance part (51) holding the linear part (41) of a ring-shaped member (4), a flexible wire is used as a ring-shaped member (4). Even when it is used, it is possible to reliably form the linear portion (41).
However, in this invention, it is also possible to employ | adopt the structure which attaches the base end part of a ring-shaped member (4) directly to the front-end | tip part of an elastic body (3) not via a connection member (5). In this case, the linear portion (41) may be formed by means such as inserting the base end portion of the ring-shaped member (4) through a linear cylindrical body.

The attachment portion (52) is rotatable with respect to the distal end portion of the elastic body (3) (see FIG. 4).
Thereby, the angle with respect to the elastic body (3) of a ring-shaped member (4) can be changed freely, and it becomes possible to apply widely to the existing filters of various sizes, thicknesses, and shapes.

Hereinafter, a method of using the jig according to the present invention will be described.
As shown in FIGS. 5 to 7, the jig according to the present invention covers an existing filter (6) built in an air conditioner with a rectangular sheet-like simple filter (7) made of a nonwoven fabric or the like, and this It is used by fixing the jig (1) to the existing filter (6) from above the simple filter (7).
Specifically, the four elastic bodies (3) of the jig (1) are extended in four directions, and the ring-shaped members (4) at the respective tips are engaged with the four corners of the existing filter (6). Stop. As a result, the jig (1) is fixed to the existing filter (6). As a result, the simple filter (7) is fixed to the existing filter (6) while being pressed by the jig (1).

As described above, the jig (1) according to the present invention is configured to be fixed to the existing filter (6) using the elastic body (3) and the ring-shaped member (4). It can be easily and reliably fixed to the existing filter (6) having a thickness (see FIGS. 5 and 6) and to the existing filter (6) that is curved (see FIG. 7).
In addition, although not shown, the jig (1) according to the present invention is fixed even if the existing filter (6) has a rounded corner or a polygon other than a quadrangle. can do. Furthermore, as will be described later, the existing filter can be fixed even if it has a shape (circular shape or the like) that does not have corners.
Moreover, since the jig | tool (1) based on this invention can attach a simple filter (7) with respect to an existing filter (6) reliably only with one jig | tool (1), the operation | work of attachment or removal is carried out. It can be performed efficiently in a short time.

  The jig (1) according to the present invention is a straight line in which the ring-shaped member (4) is substantially perpendicular to the extending direction of the elastic body (3) in the vicinity of the connecting portion with the elastic body (3). When the ring-shaped member (4) is locked to the four corners of the existing filter (6), the base end portion of the ring-shaped member (4) is a linear portion. (41) expands and the lock is very difficult to release.

Hereinafter, this operation will be described in more detail.
When the ring-shaped member (4) does not have the linear portion (41) (see FIG. 8A), when the ring-shaped member (4) is locked to the four corners of the existing filter (6) Moreover, since the base end portion of the ring-shaped member (4) does not expand, the length (D) of the hooked portion is shortened, and the locking is very easily released.
On the other hand, when the ring-shaped member (4) has the linear portion (41) (see FIG. 8B), the ring-shaped member (4) is replaced with the four corners of the existing filter (6). When the ring-shaped member (4) is locked, the base end of the ring-shaped member (4) expands, so that the length (D) of the hooked portion becomes long, and the lock is hardly released.
That is, the linear part (41) of the ring-shaped member (4) plays a very important role in order to securely lock the ring-shaped member (4) to the four corners of the existing filter (6). In particular, when the corner portion is rounded, the length (D) is shorter than when the corner portion is sharp. Therefore, it is very important to provide the linear portion (41).

If the overall length of the linear portion (41) is too short, there is a possibility that the action of reliably locking the ring-shaped member (4) to the corner of the existing filter (6) may not be obtained. It is preferably at least 25 mm or more, more preferably 30 mm or more.
FIG. 9 is an example in which the length of the linear portion (41) is long, and by making it long in this way, the length (D) of the catching portion becomes long and the locking becomes more difficult to release. However, it is necessary to make it sufficiently shorter than the entire length of the ring-shaped member (4).
In addition, it is more preferable that the length of the linear portion (41) can be adjusted because it can be adjusted to an optimum length for existing filters of various sizes and thicknesses. The configuration for adjusting the length is not particularly limited. For example, the holding portion (51) is composed of two members, a member (51a) having a female screw and a member (51b) having a male screw, and the length of the meshing portion of the screw. The structure which adjusts length by changing can be illustrated (refer FIG. 10).

  Moreover, the structure by which the above-mentioned holding | maintenance part (51) is crimped flat exhibits the effect | action which makes the latching of a ring-shaped member (4) still more difficult to remove | deviate. That is, when the ring-shaped member (4) is locked to the four corners of the existing filter (6), the flat surface of the holding part (51) moves almost closely to the surface of the simple filter (7). It becomes difficult, and the locking of the ring-shaped member (4) becomes more difficult to come off. Moreover, if a protrusion or an unevenness is provided on the flat surface, the protrusion or the protrusion will bite into the surface of the simple filter (7), and the holding part (51) will be more difficult to move.

11 thru | or FIG. 13 is a figure which shows a mode that the existing filter (6) (refer FIG. 5 thru | or FIG. 7) to which the simple filter (7) was attached with the jig | tool (1) is attached to the air conditioner. . The mounting operation is completed by closing the lid (louver) (8) from the state shown in the figure.
As shown in the drawing, the jig (1) according to the present invention has various forms of air such as a home wall-mounted air conditioner (see FIG. 11), a ceiling-embedded cassette air conditioner (see FIG. 12), a fan coil (see FIG. 13), and the like. It can be widely applied to a harmony machine and is very versatile.

As shown in FIGS. 11 to 13, by using the jig (1) according to the present invention, by attaching the simple filter (7) so as to cover the existing filter (6) built in the air conditioner, Most of the dust contained in the air taken in from the intake port of the air conditioner can be captured by the simple filter (7). Therefore, the frequency of cleaning and replacement of the existing filter (6) can be greatly reduced.
Moreover, by using the jig | tool (1) which concerns on this invention, the operation | work of attachment and removal of a simple filter (7) can be performed easily in a short time. Moreover, the simple filter (7) can be easily and reliably attached to the existing filter (6) incorporated in various forms of air conditioners.

The jig (1) according to the present invention can also be applied to an air conditioner outlet provided on a ceiling, a duct for taking outside air into a room, an indoor circulation type ventilation device, and the like.
FIG. 14 is a view showing an example of the air outlet (9) of the air conditioner to which the jig (1) according to the present invention is applied.
The air outlet (9) opens to the ceiling (10) in the room, and blows out warm air and cold air sent through the cylindrical pipe (11) toward the room.
An existing filter (6) as shown in FIG. 15 is mounted in the pipe (11) in advance or retrofitted.
The existing filter (6) is obtained by sewing a non-woven fabric (62) inside a circular ring (61), and has a circular shape (disc shape) as a whole.

FIG. 16 is a view showing a state in which a simple rectangular filter (7) is attached to the above-described circular existing filter (6) by using the jig (1) according to the present invention. ) Is a front view, and (b) is a back view.
As for the attachment method, the surface of the existing filter (6) is covered with the simple filter (7), the jig (1) is arranged above (front side) of the simple filter (7), and then the four elastic bodies (3). Is extended toward the four sides, folded back toward the back surface of the existing filter (7) in the middle, and the ring-shaped member (4) at each tip is turned to the back surface of the existing filter (7). At this time, the four corners of the simple filter (7) are also folded toward the back surface of the existing filter (7). Then, the ring-shaped member (4) provided at the tip of one elastic body (3) is locked to the connecting member (5) provided at the tip of another opposing elastic body (3) (FIG. 16). (See (b)).
Here, since the connecting member (5) is formed in a substantially T shape as a whole, the ring-shaped member (4) can be easily and reliably locked to the connecting member (5). .
As described above, the jig (1) is fixed to the existing filter (6). As a result, the simple filter (7) is pressed by the jig (1) and fixed to the existing filter (6). Is done.

As described above, the jig (1) according to the present invention can attach a simple filter to a circular existing filter having no corners.
Therefore, as shown in FIG. 17, the simple filter (7) is applied by the method shown in FIG. 16 to the existing filter (6) mounted in advance or retrofitted inside the duct (12) for taking outside air into the room. ) Can be attached.
